Rsync error cannot do ssh and transfer file

linuxbee1 · 06-23-2008, 02:01 PM

Hi,

I am trying to transfer a folder from one machine to another machine using ssh and rsync. I doing rsync has root. I am getting the following rsync error.

rsync: Failed to exec /var/lib/postgresql/7.4/: Permission denied (13)
rsync error: error in IPC code (code 14) at pipe.c(83)
rsync: writefd_unbuffered failed to write 4 bytes: phase "unknown" [sender]: Broken pipe (32)
rsync error: error in rsync protocol data stream (code 12) at io.c(1099)

I tried changing the file permissions too...

Could you post your rsync command? The permission error could be on the source system or the target system

My rsync code:

rsync -av -e /var/lib/postgresql/7.4/ ssh root@<ip address>:/var/lib/postgresql/7.4/

Are you running as root on the source machine? Is /var/lib/postgresql/7.4 a network share on either the source or target machine (that can cause problems if running as root)?

Is your 'ssh' in the right place ? Should it be ...

Code:

rsync -av -e ssh /var/lib/postgresql/7.4/ root@<ip address>:/var/lib/postgresql/7.4/

ssh is in the right place. I am doing ssh on the source machine to connect to the target machine.

LiamFromLeeds · 06-23-2008, 04:08 PM

Are you logged in as root on the source machine ?

linuxbee1 · 06-23-2008, 04:12 PM

No. I am not logged in as root on the sourse machine. I am accessing target machine as root.

LiamFromLeeds · 06-23-2008, 04:18 PM

So could the permission denied error be "read" permission on the source machine then? What does the following return on the source machine?

Code:

ls -l /var/lib/postgresql/7.4/

What Liam means is that "ssh" should immediately follow tha "-e" option - you are trying to use the "/var/lib/....." as the remote shell

Does your user have read access to the postgresql files?

linuxbee1 · 06-23-2008, 04:27 PM

Yes. It has read access. I changed the user permission.

I definitly think your command is wrong and you need to rewrite it as I suggested earlier to ..

Code:

rsync -av -e ssh /var/lib/postgresql/7.4/ root@<ip address>:/var/lib/postgresql/7.4/

If you man ssh you'll see an example ..

Code:

 rsync -az -e ssh ~ftp/pub/samba/ nimbus:"~ftp/pub/tridge/samba"

The important thing is that "ssh" follows the "-e". This is telling rysnc to use the ssh protocol for the connection. Note in the example the source target is local and specified first and the remote target is specified second, just as you want.

I think the other clue is that your error is "failed to exec". Its trying to run /var/lib/postgresql/7.4 because you've told rsync this is the shell you want to use
